Describe when you use a solid line or a broken line when graphing inequalities. what does each type of line mean?

Graphing Linear Inequalities differs from graphing regular linear equations. That is it has certain rules to be followed to draw the graph.

First, rearrange the equation as y in the left and other terms in the opposite side.Check for the line: y= , y≤ and y≥ comes with straight line where as y< and y> comes with a dotted (broken) line.Shading: If y> greater than or y≥ greater than or equal is present then the space above the line has to be shaded. If y< less than or y≤ less than or equal  is present then the space below the line has to be shaded.

Thus if the equation has y < or y > then we use broken line and y= , y≤ and y≥ then we use solid line.

The answer is -1,19,39,59
